Yes, fire extinguishers eventually expire. However, the good news is that a properly stored fire extinguisher can last a decade or longer. They don’t have an expiration date on the canister, but you can check the manufacturing date on the “UL” nameplate near the classification information. Maintenance will also give your fire extinguisher longevity. Check the gauge at the top of the extinguisher every month. You'll want to make sure the gauge needle is in the green section, and if a hose or nozzle has been used or damaged, you need to replace it.

Yes, you should seal and cap an unused chimney to protect it from damage. Sealing the structure helps prevent moisture damage, which can lead to issues like cracks, spalling, efflorescence, and damaged mortar joints. Capping the chimney is also crucial to prevent blockages, damage from invasive critters, and downdrafts, while still allowing for proper air ventilation to manage moisture. For the best results, consult a chimney professional to select the right type of chimney or flue cap for your home. It's also wise to continue with annual chimney inspections to maintain the structure's integrity.

No. Removing the cause of concern will only lead to deeper concern. You cannot use any fire-powered appliance like a fireplace or furnace without an escape route for the smoke and fumes. If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

Wiring a light switch wrong can cause a fire if the incorrect wiring causes arcing, meaning the current jumps uncontrolled from one conductor to another. Loose wires or worn wires that are not repaired or replaced can cause arcing. If you’re not 100% sure you can do the job safely, don’t attempt to wire a light switch on your own.
